Measurement-induced spatially nonuniform fluctuations of the local particle number and their crossover in a quasiperiodic free-fermion chain
Toranosuke Matsubara, Kazuki Yamamoto
We study continuously monitored dynamics of a quasiperiodic free-fermion chain defined on a Fibonacci lattice. We focus on fluctuations of the local particle number, which exhibit…
Measurement-induced phase transitions for free fermions in a quasiperiodic potential
Toranosuke Matsubara, Kazuki Yamamoto, Akihisa Koga
We study the dynamics under continuous measurements for free fermions in a quasiperiodic potential by using the Aubry-André-Harper model with hopping rate and potential streng…
Modulated honeycomb lattices and their magnetic properties
Akihisa Koga, Toranosuke Matsubara
We propose a family of modulated honeycomb lattices, a class of quasiperiodic tilings characterized by the metallic mean. These lattices consist of six distinct hexagonal prototile…
Triangular and dice quasicrystals modulated by generic 1D aperiodic sequences
Toranosuke Matsubara, Akihisa Koga, Tomonari Dotera
We present a method for generating hexagonal aperiodic tilings that are topologically equivalent to the triangular and dice lattices. This approach incorporates aperiodic sequences…
